Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration through a membrane.
Identify the type of membrane involved in osmosis: Osmosis requires a semipermeable membrane, which allows only certain molecules or ions to pass through it by diffusion.
Differentiate between types of membranes: A permeable membrane allows all substances to pass through, a non-permeable membrane does not allow any substances to pass, and a semipermeable membrane selectively allows certain substances, like water, to pass.
Recognize the role of a semipermeable membrane: In osmosis, the semipermeable membrane permits the passage of water molecules while preventing the movement of solute molecules.
Conclude that for osmosis to occur, water must pass through a semipermeable membrane, which is the correct answer to the problem.
